if only one could obtain enough epoxy to fill a dumpster haha

700m/s??? I think you could safely test terminal range on a GB... If 700m/s doesn't get it past 1mile, nothing will...

Why do i all the sudden feel like me and the decimater are just a kid and a rubber band gun???

No need to be so drastic, I have access to stainless steel tube offcuts so pretty thick endcaps should suffice. It's in the pipeline, though at the moment the focus is on my HPA auto devices.

And it won't. I can tell you that it'll probably hit a bit short of half a mile out.

Still a bloody long way though. You could have fun at the local driving range.

That was my point... that anybody says they shoot golfballs a mile with a sub 1000fps muzzle velocity is deluded... 1/2mile is possible, but only due to loft from backspin... I do know that when I've put fins on Gb's, they are more accurate but distance is cut almost in half...

What have you been up to?

Oh, so that's where it landed. I guess that means I should stop messing with the gravity cannon.

So you're actually partly responsible for Scotland's relatively low life expectancy

I'm responsible for a whole lot more than that...

i have a question
if you fill a chamber with some gas, then pump in some air, then ignite the gas, trapping the gas with a ball valve, then flip the ball valve, would the ball valve hold the pressure or would it leak?

The pressure is only momentarily generated by the heat. It would most likely spike then return previous pressure before you could turn the valve.

After combustion takes place, a vacuum results from gas products being turned into liquid (water). Basically a gun that sucks things in, handy

EDIT: and you lose thermal energy; even less pressure.

As the others said, the pressure pretty much returns to pre-ignition levels. That's what i've experience anyway when a disk hasn't burst.

One method of storing pressure from combustion is to use the hot gasses generated to drive a piston which compresses air in a chamber past a check valve. The Sims-Dudley Dynamite Gunused this effect.



Here's what a combustion powered pump could look like:

200x for a first hybrid! WHat will you do to beat that?
